Application ed September 28, 1911.y Serial1 No. 651,728.

To all Vwhom it may concern:

Be it known that I, JOSEPH KUTYLA, Va subject of the Czar of Russia, residing at McDonald, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in SemaphoreSignals, of which the following is' a', specification, reference being had therein to the accompanying drawing. A

This invention relates to a semaphore signal, and more particularly to a safety device for railways.

The object of my invention is to provide a. signal that will be intermittently actuated 'during the passage of a train over a block or section of track to display a danger signal and prevent rear-on collislons.

My .invention aims to provide a semaphore signal that can be installed atintervals whereby one or more of the signals will be actuated by a train to notify a train approaching inthe rear that it is in the vicinity of a preceding train, the arm of the semaphore beingu placed at a danger position for daylight signaling and the lens of the semaphore being placed in position in connection with a lantern for night signaling. The danger signaling is automatic and can be advantageously used upon a curved section of track where-the signals are closely arranged in order that one of said signals will always be in view of the engineer or fireman of a train approaching in the rear of a preceding train.

It is a well known fact that the blocks of the present signal system are often of considerable length, even .upon curved sections of railroads, and that when a train is rounding a curve in one block, it is often imposmanner rear-on collisions often occur, and it isthe principal' object of this invention to eliminate the destruction of rolling stock and lives due to accidents, by providing simple and inexpensive devices that can be closely arranged, whereby the devices will be successively actuated by a train' or Single The invention will be better understood when reference is had to the drawing and detail description thereof.

in the drawing like numerals designate corresponding parts throughout the several views, in which Figure lis a from elevation or a signal connection .with a rail, Fig-2 is a side elevation of the signal rail, partly broken away, showing the actuating mechanism in elevation, Fig. 3 is a diagrammatic viewl illustrating the location of the signals relatively to a straight and curved section of a track,

Fig. 4 is a horizontal sectional view of a portion of the semaphore arm, and Fig. 5 is a sectionaljdetail.

n The reference numeral 1 denotes one of the rails of a track 2 and this rail has the base flange 3 and the head thereof cutaway, as at 5, the cut away portion being opposed by a side plate 6 bolted or otherwise connected, as at. 7 to the rail 1, adjacent tothe ends of the cut away portion 5. In the cut away portion 5 are arranged two curved shoes 4 having the confronting ends thereof pivotally connected together by a' pin 8. The outer ends of the shoes 4 are provided with pins 9 and-these pins extend into longitudinal slots 1() provided therefor in the web 11 of the rail. The web 11, beneath the shoes 4, is provided with pins 12 projecting into the cut away portion 5 of said rail and connecting these pins is a bar 13v having the ends bent to provide springs 14 that engage in the groovesA 15 provided .therefor in the under side of the curved shoes 4. The springs 14 normally support the inner ends of the shoes 4 in a plane -iiush withA the tread of the rail 1, and the bar 13 limits the downwardmovement of the inner when a train passes over the rail, the inner ends of the shoes will be rapidly depressed. aby the wheel lianges. I

sible tol observe the signal of the block be- Vforeentering the preceding block. In this The rail 1 rests upon the .end-of a casing 16 that eXtendsrQm said rail to a signal post 17. in the ends of the casing are bearings 18 supporting revoluble sheaves 19 and` shaft 26 journaled in the post 17. rlhe ends of the shaft 26 protrude from the outer sides of thepost and fixed upon the ends 'of shaftie a' yoke 2'?. A,This yoke vhas a sem- `,t en ds upwardly over the yoke 27. The ob-' ject of this spring is to lower the semaphore arm, 28 and eleva-te the lens holder '29', whereby the lensy 30 will f be positioned 1n front ,y of the lantern 31 to display a red or danger signal.

In practice, the tension of the springs 14 is greater than that of the spring 34, consequently the pivoted curved shoes 4 will be normally retained in an elevated position with the cable Q0 taut, and the lens holder 2.9 in `a lowered position. When the danger of the wheel engages the shoes 4, the confronting pivoted ends of said shoes are depressed and the outer ends of said shoes slide within the pocket 5 and are retainedA therein by the pins 9.` When the shoes 4 are depressed, -the cable 2O shifts upon the sheaves 19 and '23 allowing the spring 34 to raise the lens holder 29 and lower the semaphore arm 28. The semaphoreA arm 28, in a lowered position, indicates danger during the day and the lens holder 29 in ah elevated position coperates with the lantern 31 in displaying a danger signal at night. Immediately upon the iiange of a wheel releasing the pvoted shoes 4the springs 14 restore said shoes to their normal position and lower the yoke 27.

As illustrated in Fig. 3, the., signals upon a curved section of track 37 are more closely arranged than upon the straight section 38. This is in order that a fireman or engineer can easily observe the signals, particularly when the curve is very sharp' and a moun Copies ot this patent may be obtained for ve cents each, by addressing Washington, D. C.

- mamas tain 39 would obstruct the View of signals arranged the same distance apart as on a straight section of track. The signals are successively operated by a train and it is possible for an engineer following a preceding train to readily determine the distance between the trains and regulate the speed of the following train accordingly. ,The signal has been especially designed for mountainous districts and for sharp curves where the majority of rear-on'collisions occur. It can be readily used in ceimection with the present type of block signal, and as the signal is independent of any electrical ,cir-cuits, it can be readily maintained at a comparatively small cost. i

In a semaphore signal, the combination with a rail having a cut away portion, .a post located adjacent to said rail, and a semaphore arm pivotally supported by said post, of a pair of curved shoes pivotally connected together at their upper ends and sliclably connected at the lower ends to the of being engaged by the flange of a wheel whereby said shoes are depressed, a bar car- .ried by the cut away portion of said rail and provided at each endwith a resilient member, said members engaging said shoes for normally maintaining them in an ele- `vated position, a shaft journaled in the upper end of said post and to which said semaphore arm is connected, a crank carried by said shaft, a cable connecting said shoes and said crank, and means carried by said shaft for moving said semaphore arm to a danger position when said shoes are depressed.

In testimony whereof I aiiix my signature in the presence of two witnesses:
